To all whom it may concern:

Be it known that 1, WILLIAM J. HoLooMB, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ghio, have invented certain new and usefu'ldmprovements in Combination Locks for Car-Doors; and I do hereby declare the followingto be a full, clear, and exact descriptionof the invention, such as will enable the purpose specified, and which can be opened only by an individual having knowledge of the combination, .and after the individual tumblers of thelock have been set in the position required for permitting the movement of a three par-tbolt to inoperative position. I

A further obj set is to provide, in a lock of the type indicated, a plurality of tumblers each mounted on a separate axis, and a three part bolt for cooperation with the tumblers so mounted.

A still further object to provide, in connection with a notched bar, a plurality of dogs cooperating locking bolt controlling the dogs and acting to release them from the notched bar, and a plurality of tumblers each mounted on a separate axis, the movement of the bolt to inoperative position for releasing the dog depending upon the relative position of the tumblers.

A still further object isto provide for throwing the boltsby the use of a key, with which the dials may also be set, and to provide an independent bolti operating device controlled by rotary or longitudinal movement, one element of the last named device constituting a seal bar.

With the foregoingand other objects in view-the invention consists in the novelconstruction, combination and arrangement of .e'lementshe'reinatter described and claimed, it being understood that modificat ons or variations in construction may be made within the scope-of the claims, without departing from the spirit of the invention. t

' In the accompanying drawings Figure 1 1s a view of thelock in elevation, as applied to theside of a box car, the pivotwiththe bar, a three part ally mounted locking element being shown at the right andmounted on' the car door.

Fig. 2 'is an end elevation of the lock casing,looking from the left in Fig.1.

Fig. 3 is a view showingthe operative" ele- 1 ments in elevation, the face plate of the'casing being removed. V Fig. 4 is a similar view, the" three partbolt having been thrown, and the notched bar in the lower portion of the viewbeing disen- ,gaged.

Fig. 5 is a horizontal section, otFig. 3. 1

Figs. 6 and 7 are horizontal sections ofthe devices for throwing the threepart'bolt;

Fig. 8 is a sectionon line 8-8 of Fig. 7;

Fig. 9 is a detail of construction described below. a

The reference number 10 indicatesthe casing per se of the lock, to be mounted on the side of a car, and the faceplate of the lock "is designated 12. The tumblers are shown" at 1 1, 15 and 16, and are provided with notches 17, each t'umbler'being further provided with a deep notch or'slot 18. These tumblers are rotated by a key 2.0 having a socket engaging the square ends 21 otthe pins '22, the'sepins havingconnection with the dial plates.

The dial plates 2%, 25 and 26ers provided with'a series of numbers; as shown, and thesenumbers are to be set in a predetermined relation, in order that all of the slots 18 may be so positioned that the bolt will be permitted below. 1

A bar 30 carries pins 31 and-32, for cooperation with. the slots18 of r'n'embersl l and 16, and a vertical bar 84: carries a pin 35 for to operate for releasing the dogs referred to r i I V v90 cooperation with the slot'18 of tumbler 15.

The bar-.8 1, which'has one endpivoted, is providedwith a slot 86, and a pin or screw 37 passing through the bar80 cooperates with the ,slot,"'an.d causes'the bar .80 tobe thrown when the bar 3dis moved from the position shown in Fig.8. to that shown in Fig. 1. As the result of this constructioinall of the pins coiiperating with the slots 18 move at the same time,

gle levers 45 and pivotally connected with and if the tumblers are in correct, position for opening the'lock, th i will of 105 bar 30, so that the dogs are released from bar it when the tumblers are in the posit-ion just indicated, and when the bars 30 and 34 are thrown. For convenience these bars and 34 are together termed a three part bolt.

The notched bar 44 is pivotally connected with the car door by straps 44, and swings downwardly to vertical position when released from the lock.

The upper end of bar 34 projects into a slot 47 in sliding bar 48, and threaded into the end of the latter is a seal bar or stem 4:8 the shank and threaded portion of which passes loosely through a block 49.

Sliding bar l8 is guided by threaded pins 48'.

The laterally extending stationary block 429 has a transverse slot 50 therein accommodating a collar 51 loosely mounted on the seal bar. A pin 52 may be passed through registering apertures in bar d8 and the threaded portion of the seal bar, preventing the rotation and withdrawal of this bar, longitudinal movement of element 48 and the seal bar being permitted for shifting the three part bolt 01* the look.

If this pin 52 is withdrawn and passed through registering apertures in the collar and the seal bar, the collar will prevent longitudinal movement of the seal bar, but will permit of rotation, and the threaded portion cooperating withthe threaded boreof the member 48 will permit that bar to be shifted by imparting rotary movement to the head-5d.

If the seal bar and operating member are withdrawn by removing the pin 52, and unscrewing the end ot this bar from the bar 4.8, the three part bolt may be operated by causing key 20 to engage the square end 21 of the pin 30 which serves as a pivotal element for hart-34.

The flexible element 55 oi seal 56 may be passed through registering apertures of the element 4-9 and the seal bar lS Havin thus described the invention, what I claim'is:--

1. In a device of the class described, a casing, a plurality of tumblers mountec therein in different planes, an element adapted to be locked in a predetermined position with in said'casing, locking members for engage ment with said element, locking members for operating said members, bars'adapted to control said pivoted operating members, said tumblers being adapted at times to prevent operation of said bars, and operating; means for said bars.

2. In a device of the class described, a casing, tumblers mounted therein and provided with radial slots, an element adapted to be locked in a predetermined position within said casing, pivoted locking members for engagement with said elements, bars for controlling the operation of said pivoted lock- 'or engagement at times in said tumblers, and an operating memid bars, said operating member l have a seal extended thereadevice or" t 1e class described, a casalers moun ed therein on independs and each including a radial slot,
